'Swears' in the Bible

Or when a person swears, speaking thoughtlessly with [his] lips, to do evil or to do good {with regard to} anything that {the person} in a sworn oath speaks thoughtlessly, but {he is unaware of it}, he will be guilty {in any of} these.

or he finds lost property and lies about it and swears {falsely} {in regard to} any one of these things by which {a person} might commit sin,
